AGRONICA.
 
En la mayoria de sistemas agropecuarios se esta utilizando la Informàtica y la últimas tecnologias para optimizar y facilitar los trabajos de campo lo que se llama AGRONICA
Se usa los sensores: de movimiento, de temperatura (termocuplas), de humedad, de presencia, etc.  

La  Interacción  del computador, la  electrónica, la informática y las  ultimas tecnologías  en el  sector agropecuario han creado la AGRONICA y  han cambiado el modelo tradicional manual, llegando a la automatización y al control  dinámico con potables, smartphones).


Con la introducción de la  agrónica la agricultura de precisión ha evolucionado , se puede crear bases de datos de todas las clases , especies ,variedades y ecotipos de plantas agrícolas; Con la agrónica la variedad de climas y suelos debidamente modelados permiten  la mejor utilización de recursos naturales  y energéticos .

Las bases de datos mediante la agrónica nos permiten diversificar los cultivos en base de  las características del suelo, agua,planta , con rotación  ( en base de cultivos anteriores )  para optimizar  la producción, lograr calidad  y minimizar los costos de producción.

En la agrónica con el uso adecuado de las herramientas informáticas de hardware (en base de la nanotecnología, sensores) y Software (programación con algoritmos distribuidos)  , se puede crear Bancos de datos sobre cultivo de tejidos  de las diferentes  plantas  agro industriales, con la agrónica se incorpora la Realidad virtual, la inteligencia artificial, los sistemas expertos, que interactuan mediante  el ordenador con los diferentes portables . 

La Agrónica y sus herramientas nos  permite diagnosticar y modelar las tendencias  a través del tiempo con el uso de múltiples variables para lograr el máximo rendimiento, identificar las plagas y  enfermedades que atacan y recomendar, con la agrónica los agroquímicos necesarios ya probados experimentalmente en relación con múltiples variables controlables. La Agrónica ha permitido el uso de las redes de neuronas, la genètica , la mineria de datos para crear Sistemas Informàticos propios y se han patentado  prototipos específicos para tareas y labores agropecuarias de campo e invernadero.

Special session

Ambient functionality

Organizer: Pekka Silvennoinen, VTT, Finland

Contact: pekka.silvennoinen@vtt.fi

The motivation for this session is based on a vision of a future where there will be a number, however large, of processors integrated

into artefacts in our environment. These objects will have an identity, an IP address of their own, or at least a tag attached to them, so

that they can be activated and enabled to receive and transmit RF signals carrying information on their state, behaviour and location.

The sensors will communicate autonomously. This is an era in which wireless internet will connect objects rather than just people.

Radio frequency identification (RFID) is a major technology facilitating ambient intelligence and communication. Such short-range

radio systems will provide the means to embed a degree of intelligence into our immediate environment. Other types of

communication systems are foreseen on a larger physical scale.

Contrary to the common hype, not every single sensing device need be smart. There may be a lot of rather stupid artefacts possessing

just a minimum amount of memory and even no power source of their own. The intelligence is rather placed in the network in a

smart way or handled by a person or an artefact moving physically across the network. This is why the title of our session refers to

ambient functionality rather than intelligence.

RFID is spreading to many places and is being married with many other technologies. Some applications are well advanced while

others call for further development. This applies to new RFID tags and sensors, to their fabrication by novel techniques, such as

MEMS, and to their integration into modules. For a wireless processor network to be useful, as an independent agent controlling

systems, managing services or serving the needs of an individual, one needs to develop application interface middleware to fit the

network to existing infrastructure. And while new concepts are tested in the marketplace, one has to study and improve their

acceptance by the public at large. In some cases it is relevant to ensure that a potential user is properly authorised to access the

network and subscribe to the information therein.

This is why the whole value chain from the semiconductor industry to telecom vendors and service developers and providers has a

vested interest at stake. A coherent interplay between these stakeholders and an orderly introduction of new terminal equipment and

services serve the best interests of not only the industry but also the end-users.

In order to address the entire value-chain from research to production, the session is intended to explore how theoretical inventions

and laboratory experiments can be carried through to commercial products and market launches. One can only imagine how many

bright ideas are needed to come up with a commercial product . and how many more for a successful product! Research,

development and industrial testing should be carried out in parallel not in linear sequence.

Ambient functionality can be based on autonomous wireless sensor networks, or RFID-enabled mobile handsets can be used as a

gateway. In hot spot areas the information can be shown on large fixed displays. All these approaches, and their combinations, will

certainly find their uses. The emphasis in the papers in this session is on the application where the information is received directly by

an individual or a group of people.

Most people almost always have a handset available as the penetration of mobile phones is already exceeding 100 per cent in some

communities. A mobile phone is handy when seeking additional information in a system where the intelligence is smartly located

rather than dispersed all over. If the microchip has no power source of its own, it can be interrogated by smart devices, such as a

cellular phone or personal electronic assistant. The sensor can catch the energy from the handset radiation field. And finally,

handheld devices equipped by camera facilitate an element of security.

sensor networks  An Overview 
SENSOR NETWORKS  ARE DENSE WIRELESS NETWORKS OF SMALL, LOW COST SENSORS, WHICH COLLECT AND DISSEMINATE ENVIRONMENTAL DATA. WIRELESS SENSOR NETWORKS FACILITATE MONITORING   AND CONTROLLING  OF  PHYSICAL ENVIRONMENTS FROM REMOTE LOCATIONS  WITH  BETTER ACCURACY. THEY HAVE APPLICATIONS  IN A VARIETY OF FIELDS  SUCH AS ENVIRONMENTAL MONITORING , MILITARY PURPOSES  AND GATHERING SENSING  INFORMATION  IN INHOSPITABLE  LOCATIONS . SENSOR NODES  HAVE VARIOUS  ENERGY AND COMPUTATIONAL CONSTRAINTS BECAUSE OF THEIR INEXPENSIVE NATURE AND AD-HOC  METHOD  OF  DEPLOYMENT . CONSIDERABLE RESEARCH  HAS BEEN FOCUSED AT OVERCOMING THESE DEFICIENCIES THROUGH MORE ENERGY  EFFICIENT ROUTING , LOCALIZATION ALGORITHMS AND SYSTEM DESIGN . OUR SURVEY  ATTEMPTS TO PROVIDE  AN OVERVIEW  OF THESE  ISSUES AS WELL AS  THE SOLUTIONS PROPOSED IN RECENT RESEARCH  LITERATURE.   ,
 
 
sensor networks hold a lot of promise in application where gathering sensing information in remote locations is required . it is an evolving field, which offers scope for a lot of research.
Their energy- constrained nature necessitates  us to look at more energy efficient   designs and operation we have done a  survey on the various issues in sensor networks. like energy efficiency, routing  and  localitation and the various schemas proposed for these issues and have given brief descriptions of these schemes. Further work is necessary in the areas of media access control, segurity and privacy
